Ready, steady, skate – dozens of daredevil skaters were slipping and sliding across the ice in Sheffield as an unusual extreme sport visited the city.
The competitors were taking part in a Red Bull Crashed Ice event in the latest UK qualifying round.
The high-adrenaline sport involves four people per race skating around a 440-metre track, complete with steep turns and vertical drops.
The sport allows for full contact between racers, who can reach speeds of almost 40mph as they make their way around the course. The two fastest people in each race make it through to the next round.
The 30 racers were at iceSheffield in Attercliffe, with the 10 fastest competitors qualifying for an international event in Belfast, Northern Ireland, later this month.
The sport has been in existence since 2001, taking place at venues across the world.
A spokesman for the sport said: “The whole race is held on a steep downhill track dotted with chicanes, jumps and rollers. Pushing, sliding and sprinting are all on the agenda as the athletes race down the course, but the rules are very simple; first to the bottom wins.
“Skaters descend a steep ice canal filled with bumps, jumps, rollers and obstacles four-at-a-time, jostling for position as they reach speeds of up to 60kph. With only the top two riders going through to the next round, competition is fierce.
“The sport most similar to ice cross downhill is probably ski cross. In this discipline, skiers descend a snow course featuring jumps, rollers and banked corners four-at-a-time, with the fastest two athletes progressing to the next round.
“While physical contact is not officially permitted, the high speeds and twisty courses make for spectacular action and plenty of crashes.”
